Construction mastic for commercial buildings in St Fillans
On a new build, the mastic package is one of the last trades through each area, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers, sealing plot by plot or floor by floor as areas are released. We work on window and door perimeters, internal decorators’ caulk and floor and skirting junctions, and what we are called in for most is early adhesion failures on new external joints and frame perimeters left unsealed or poorly sealed. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in St Fillans, that means joint design, primers and backing rod as standard.
In smaller places such as St Fillans, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Why it’s worth doing now in St Fillans
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. If the frame is life-expired, we will tell you. Around smaller places like St Fillans, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Why appoint us
- One phone line for London, the South East and Scotland

What sets the cost
Each job is priced on its own details. The things that drive the figure:
- Working within restricted access windows
- Backing rod, priming and other preparation
- The total length or number of joints
- Induction, permit and paperwork requirements
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- Any dates the work must fit around
- Specification clauses that apply
- Clear photographs of the problem areas
- Drawings or a marked-up plan, if available
Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, phone 01277 525 020 or email us.
What we’re called out for in St Fillans
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
What tends to prompt an enquiry:
- Inconsistent sealant finishes from plot to plot
- Window and door perimeters that won’t pass inspection
- Oversized or tapered gaps around new frames
- New external sealant already peeling away
Hotels like The Four Seasons Hotel (0.5 miles west of St Fillans) rarely close for long, so refurbishment mastic is phased floor by floor.
What your quote should include
- Their public liability cover
- Their plan for phasing and protecting the area
- Whether old or failed sealant will be cut out, not overlaid
- Their approach to joint depth and backing
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Rework caused by others damaging completed areas
- Frame gaps too wide for sealant, which the installer needs to correct
- Glazing units that are cracked or misted
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.
Joints and surfaces we work on
- Window and door perimeters
- Brick and block movement joints

What else we do in St Fillans
St Fillans: questions and answers
Is a smaller place like St Fillans outside your area?
Not at all. St Fillans is within our area. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.
Can you keep pace with our programme in St Fillans?
Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What happens if the weather stops external sealing?
Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems, so we wait rather than redo work.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can the building stay open while you work?
In the majority of cases, yes. Phased work can be planned so areas stay in use.
Can you work to our specification?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
